Title: Manufacture of epitaxial wafer
Inventor: MIZUNIWA SEIJI
IPC: H01L21/208
Filed: 1993-10-12
Abstract: PURPOSE:To reduce defective thyristors by a simple method without reducing a light emission luminous intensity by a method wherein the melt-back depth of a p-type layer is controlled. CONSTITUTION:A p-type Ga0.65Al0.35As layer and an n-type Ga0.4Al0.6As layer are built up on a p-type GaAs substrate to manufacture an epitaxial wafer for an LED. When the n-type layer is built up on the p-type layer, the p type layer is melted back with n-type layer growth solution by 0.5-5mum and then, successively, the n-type layer is built up. If the supersaturation rate is increased to change the melt-back depth, the luminous intensity is declined to 0.8 approximayely. If the melt-back depth is shifted in the unsaturation (melt-back) direction, although a little decline of the luminous intensity is found in the melt-back depth range less than 0.05mum, the relative luminous intensity is stable at 1.0 in the melt-back depth range not less than 0.05mum and not more than 5mum and there is no harmful influence upon the light emission luminous intensity. If the p-type layer is melted back by a depth more than 5mum, the light emission luminous intensity is declined and, if the depth is 7mum, the luminous intensity is about 0.8. Therefore. the melt-back depth should be within the above mentioned range.

Abstract: PURPOSE:To prevent the generation of a deviation between a reproducing wavelength and recording wavelength even if a hologram is exposed to a high temp. and high humidity by equalizing the film thickness of gelatin at the time of recording and the film thickness after development and forming the hologram in such a manner that moisture is not incorporated therein at all. CONSTITUTION:A liquid mixture composed of prescribed ratios of water, gelatin and dichromate is uniformly dropped onto base glass 1 to form the gelatin layer 2 contg. the dichromate which is a sensitizing agent. After the gelatin layer 2 is exposed and rinsed, an additive which can be replaced with the moisture of the gelatin is added into the gelatin and the gelatin recording medium is dried in a vacuum. Cover glass 3 is sealed on the hologram in the vacuum. The moisture in the gelatin lost by drying of the gelatin recording medium in the vacuum and sealing the same in the dry gas is compensated by the additive. The gelatin recording medium which does not contain the moisture at all and is equal in the film thickness of the gelatin at the time of the recording and the film thickness after the development is thus obtd. The generation of the deviation between the reproducing wavelength and the recording wavelength is obviated even if the recording medium is exposed to the high temp. and the high humidity.
